The latest report from the US claimed that Meng Wanzhou, the daughter of Chinese tech giant Huawei’s founder has been arrested in Canada.

Reports from Reuters News claimed that Meng Wanzhou will be facing extradition to the United States, dealing a blow to hopes of an easing of Sino-U.S. trade tensions and rocking global stock markets.

Meng Wanzhou who is also Huawei Technologies Co Ltd’s chief financial officer, raises fresh doubts over a 90-day truce on trade struck between Presidents Donald Trump and Xi Jinping on Saturday – the day she was detained.

The arrest is related to violations of U.S. sanctions, a person familiar with the matter said. Reuters was unable to determine the precise nature of the violations.

The arrest and any potential sanctions on the world’s second biggest smartphone maker could have major repercussions on the global technology supply chain. Shares in Asian suppliers to Huawei, which also counts Qualcomm Inc and Intel among its major suppliers, tumbled on Thursday.

Meng, one of the vice chairs on the company’s board and the daughter of company founder Ren Zhengfei, was arrested on Dec. 1 at the request of U.S. authorities and a court hearing has been set for Friday, a Canadian Justice Department spokesman said. Trump and Xi had dined in Argentina on Dec. 1 at the G20 summit.

Sources told Reuters in April that U.S. authorities have been probing Huawei, the world’s largest telecoms equipment maker, since at least 2016 for allegedly shipping U.S.-origin products to Iran and other countries in violation of U.S. export and sanctions laws.

Huawei confirmed the arrest in a statement and said that it has been provided little information of the charges, adding that it was “not aware of any wrongdoing by Ms. Meng”.

She was detained when she was transferring flights in Canada, it added.

China’s embassy in Canada said it resolutely opposed the arrest and called for Meng’s immediate release.

In April, the sources told Reuters the U.S. Justice Department probe was being handled by the U.S. attorney’s office in Brooklyn.
